## Abstract

A patient monitor includes a clamping device on its rear surface for securely holding the monitor on an intravenous line (IV) pole. The clamping device is operated by the user with a sliding lever located on the side of the unit. The clamping mechanism has a ratcheting device to maintain the clamping force on the IV pole applied by the user with a simple one hand pull. The sliding lever has two buttons that release the clamp from the IV pole when the buttons are depressed simultaneously. The IV pole clamping system provides a simple and reliable mechanism for securely attaching the patient monitor to a stretcher IV pole or a free standing IV pole during patient transfer.

## Claims

### Claim 1

A patient monitor adapted to receive an intravenous line (IV) pole comprising:
a housing defined by a front surface, a right surface, a left surface, and a rear surface, wherein the rear surface has a vertical length;
two opposing arms extending at least partially along the vertical length of the rear surface, wherein the two opposing arms define a channel adapted to receive said IV pole;
a sliding lever positioned on the right surface of the housing, wherein the channel is positioned closer to the right surface than to the left surface;
a ratcheting mechanism connected to the sliding lever and configured such that movement of the sliding lever causes said ratcheting mechanism to move horizontally;
a link attached to the ratcheting mechanism such that movement of the ratcheting mechanism causes said link to move; and
a clamping device attached to the link, wherein the clamping device comprises a clamping arm positioned within said channel and an extension that is connected to the link, wherein movement of the link causes the clamping arm to move from an open position to a closed position such that in said closed position the clamping arm grips said IV pole within said channel.

### Claim 2 (depends on 1)

The patient monitor of claim 1 wherein the sliding lever is adapted to move horizontally and, upon moving horizontally, causes the ratcheting mechanism to move horizontally.

### Claim 3 (depends on 1)

The patient monitor of claim 1 wherein the clamping arm and extension are configured to rotate about an axis such that movement of the extension causes it to rotate about the axis which, in turn, causes the clamping arm to rotate about the axis.

### Claim 4 (depends on 1)

The patient monitor of claim 1, wherein said sliding lever comprises at least two buttons which are used to unlock said sliding lever and release the clamping arm such that it is in an open position.

### Claim 5 (depends on 4)

The patient monitor of claim 4, wherein said channel has a diameter in a range of approximately 16 mm to 28 mm for receiving the IV pole.

### Claim 6 (depends on 1)

The patient monitor of claim 1, wherein inner walls of said channel comprise a layer of an elastomeric material.

### Claim 7 (depends on 6)

The patient monitor of claim 6, wherein said elastomeric material has a shore hardness in a range of 70-90.

### Claim 8 (depends on 1)

The patient monitor of claim 1, wherein said ratcheting system comprises a gear rack which is coupled to a pawl through a rotary damper.

### Claim 9 (depends on 8)

The patient monitor of claim 8, wherein said pawl engages a plurality of teeth of the gear rack and provides a ratcheting action.

### Claim 10 (depends on 9)

The patient monitor of claim 9, wherein said pawl has a tip configured such that it can move over the plurality of teeth of the gear rack in one direction when the sliding lever is pulled, but lock into the plurality of teeth of the gear rack when moved in an opposing direction.

### Claim 11 (depends on 1)

The patient monitor of claim 1, wherein the two opposing arms have a vertical length that is equal to at least 50% of the vertical length of the rear surface.

### Claim 12 (depends on 1)

The patient monitor of claim 1, wherein the channel has a vertical length that is equal to at least 50% of the vertical length of the rear surface.

### Claim 13 (depends on 1)

The patient monitor of claim 1, wherein one of the two opposing arms is defined by the right surface of the housing.

### Claim 14

A patient monitor adapted to receive an intravenous line (IV) pole comprising:
a housing defined by a front surface, a right surface, a left surface, and a rear surface, wherein the rear surface has a vertical length;
two opposing arms extending at least partially along the vertical length of the rear surface, wherein the two opposing arms define a channel adapted to receive said IV pole;
a sliding lever positioned on the left surface of the housing, wherein the channel is positioned closer to the left surface than to the right surface;
a ratcheting mechanism connected to the sliding lever and configured such that movement of the sliding lever causes said ratcheting mechanism to move horizontally;
a link attached to the ratcheting mechanism such that movement of the ratcheting mechanism causes said link to move; and
a clamping device attached to the link, wherein the clamping device comprises a clamping arm positioned within said channel and an extension that is connected to the link, wherein movement of the link causes the clamping arm to move from an open position to a closed position such that in said closed position the clamping arm grips said IV pole within said channel.

### Claim 15 (depends on 14)

The patient monitor of claim 14 wherein the clamping arm and extension are configured to rotate about an axis such that movement of the extension causes it to rotate about the axis which, in turn, causes the clamping arm to rotate about the axis.

### Claim 16 (depends on 14)

The patient monitor of claim 14, wherein said sliding lever comprises at least two buttons which are used to unlock said sliding lever and release the clamping arm such that it is in an open position.

### Claim 17 (depends on 14)

The patient monitor of claim 14, wherein inner walls of said channel comprise a layer of an elastomeric material and wherein said elastomeric material has a shore hardness in a range of 70-90.

### Claim 18 (depends on 14)

The patient monitor of claim 14, wherein said ratcheting system comprises a gear rack which is coupled to a pawl through a rotary damper.

### Claim 19 (depends on 18)

The patient monitor of claim 18, wherein said pawl engages a plurality of teeth of the gear rack and provides a ratcheting action.

### Claim 20 (depends on 14)

The patient monitor of claim 14, wherein said channel has a diameter in a range of approximately 16 mm to 28 mm for receiving the IV pole.

### Claim 21 (depends on 14)

The patient monitor of claim 14, wherein the two opposing arms have a vertical length that is equal to at least 50% of the vertical length of the rear surface.

### Claim 22 (depends on 14)

The patient monitor of claim 14, wherein the channel has a vertical length that is equal to at least 50% of the vertical length of the rear surface.

### Claim 23 (depends on 14)

The patient monitor of claim 14, wherein one of the two opposing arms is defined by the left surface of the housing.
